This paper seeks to provide an explanation for why corporate officers manage the disclosure of accounting information. We show that earnings management affects firm value when value-maximizing managers and investors are asymmetrically informed. In equilibrium, the strategic management of reported earnings influences investors' assessments of the market values of companies' shares. 相似文献

We present a faster, more accurate technique for estimating implied volatility using the standard partial derivatives of the Black‐Scholes option‐pricing formula. Beside Newton‐Raphson and slower approximation methods, this technique is the first to provide an error tolerance, which is essential for practical application. All existing noniterative approximation methods do not provide error tolerances and have the potential for large errors. 相似文献

经济全球化时代,两国汇率的形成是两国间博弈的结果。中国是世界上最大的发展中国家,而美国是当今世界上最大的发达国家。从博弈论角度考察,两国在汇率问题上的重复博弈能够达到一个子博弈完美那什均衡。本文对人民币和美元汇率的波动运用了博弈理论分析了双方的得益和支付,并提出了中方在汇率问题上的政策建议。 相似文献

In this paper bilateral models formalizing monthly growth of US imports and exports are employed to investigate the potential
of nonlinear relationships linking exchange rate uncertainty and trade growth. Parametric linear and nonlinear as well as
semiparametric time series models are evaluated in terms of fitting and ex ante forecasting. The overall impact of exchange
rate variations on trade growth is found to be weak. In periods of large exchange rate variations, trade growth forecasts
gain from conditioning on volatility. Empirical results support the view that the relationship of interest might be non-linear
and, moreover, lacks homogeneity across countries and imports vs. exports. JEL no. C14, C22, F31, F41 相似文献

The underwriter of an IPO has two sources of compensation for its services on behalf of the issuer. One is through a commission
(spread), the other is by buying issued shares for itself (or its affiliates) and reselling them in the post-issue market.
Profits from the former decrease along with the magnitude of underpricing while profits from the latter increase with it.
Faced with these countervailing interests, the present paper analyzes how the underwriter decides upon the pricing and allocation
of IPOs.

In this paper we use Malliavin calculus techniques to obtain an expression for the short-time behavior of the at-the-money
implied volatility skew for a generalization of the Bates model, where the volatility does not need to be a diffusion or a
Markov process, as the examples in Sect. 7 show. This expression depends on the derivative of the volatility in the sense
of Malliavin calculus.

In this paper, returns and volatility spillovers between emerging capital markets of Central and Eastern Europe, Latin America, and South-East Asia are investigated. We distinguish between spillovers from countries located in one region (intra-regional) and in different regions (inter-regional) after controlling for shocks originating at home and on the global market. Both intra- and inter-regional spillovers are significant, with the former being more pronounced than the latter. Our findings indicate that linkages between emerging markets are not solely due to their common dependence on the global capital market and highlight the importance of common factors in intra-regional interdependencies. 相似文献
